people assume that the NYI can keep his rights after july 1st--if he was a RFA they could--but because he was signed as a UFA and it was not a complete season contract--it falls into a grey area under the cba
It is not really much of a grey area.
There is no such thing as "not a complete season contract". By definition, all SPCs are for entire League Years, with salary prorated based on the number of days on a roster.
This case (and the Yashin decision before) is not based on the CBA - the CBA is silent on the matter of specific performance. This case, however is covered in the League Rules (Constitution, By-Laws, previous League rulings, etc) - which are implicitly included in the CBA.
The ruling from the Zeigler/Stein era, which was the basis for the Yashin decision, would hold here. The hypothetical question was asked - what would happen if a pending UFA sat out for all
or part of a season? The League ruled that that player's SPC would be extended by a year and the player would not become a UFA.
Since the current CBA is still silent on specific performance, it is very likely that an arbiter would rule the same as Lawrence Holden did in the Yashin decision.
